Imaging

The algorithms used for zooming in and out on Google Maps and Google Street View have made it possible to visually traverse through layers of the body – starting with a whole joint and drilling all the way down to the cellular level. The new imaging system could have huge implications in medicine because it drastically reduces the time required to analyze and compare data. Read More
As if smartphones can't already do enough, soon they may be able to scan three-dimensional objects and send the resultant high-resolution 3D images to a 3D printer that produces hyper-accurate replicas. This comes thanks to a small and inexpensive device called a nanophotonic coherent imager (NCI), which was developed by scientists at Caltech. The NCI could add 3D imaging to a variety of other devices and applications such as improving motion sensitivity in human machine interfaces and driverless cars. Read More
How would you like to be able to know the chemical composition of something, just by taking a snapshot or video of it with your smartphone? You may eventually be able to, thanks to a compact hyperspectral imaging camera being developed at Tel Aviv University. Read More
While non-invasive imaging technologies, such as mammograms or CT scans, are capable of detecting tumors, identifying whether they are malignant or benign usually involves getting out the scalpel and conducting a biopsy. Now researchers at Johns Hopkins University have developed a technique that uses magnetic resonance imaging (MRI) to noninvasively detect cancerous cells, offering the potential of supplementing biopsies or maybe one day replacing them altogether.

A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time. Read More
Ultra-thin flat lenses suitable for photography are one step closer after a team of researchers at Harvard University made a major leap forward with its prototype wafer-thin flat lens. The new lens builds on the original prototype, which we first heard about in 2012, by using an achromatic metasurface to focus different wavelengths of light at the same point. Read More
A new technique has been developed to suppress the noise in radar images of Titan captured by Cassini. The snaps are usually grainy in appearance due to electronic noise, but the new tool pulls back the curtain, providing the clearest view yet of Saturn’s largest moon. Read More
The European Southern Observatory's (ESO) VISTA survey telescope has revealed a beautiful new aspect of the Trifid Nebula, a star formation area that sits around 5,200 light years away from Earth, in the direction of the galactic center. By observing and imaging the nebula in infrared light, astronomers can look through the dust-filled, central parts of the Milky Way to expose new objects. Read More
The European Space Agency (ESA) has successfully tested its Fluorescence Explorer mission (FLEX), which is vying for a spot on the organisation’s eight Earth Explorer satellite. The mission, which aims to create global maps of photosynthetic activity, will allow for the identification of vegetation suffering degrees of stress that simply aren’t visible to the human eye. It has the potential to significantly further our understanding of the global carbon cycle, and could have an impact on agricultural management. Read More
According to a scientist from the University of Leicester in the UK, the search for missing ships and sea-crossing aircraft – such as Malaysia Airlines flight MH370 – would be much easier if existing satellites were simply used differently. Dr. Nigel Bannister is developing a system in which spacecraft that already keep an eye on the land could also turn their attention to the sea. Read More
